Specification of Letters Patent.l

Application led November 19, 1917. Serial No. 202,813.

Be it known .that I, Joux' C. Laim, a 'citien of the United States, and residing at Charleston. Charleston county, State of South Carolina, have invented certain new and useful Improvements in lVheel-Beari ings, of which the followingis aspecification. Y

The present invention relates to wheel bearings and more particularly to auxiliary bearings adapted to be added to the front wheels of motor vehicles of the Ford or Chevrolet types Without altering their structure.

It is the principal object of this invention to provide auxiliary bearings which may be added to the wheels of motor vehicles of the types mentioned Vwithout altering the original construction and which will pre-` ventor reduce the liability to wear and def'ormation incident ,to these bearings.

Other objects and features of the invention will be apparent from the description taken in connection with the drawing.

In the single figure of the drawing which is a sectional elevation I have illustrated a ort-ion of a front wheel of the Atype used in Ford or Chevrolet motor vehicles. This wheel comprises a, hub 10 which i'srotatively s upportedon the spindle l1- by means of two ball bearings 12 and 13. The inner bearing 12 includes a cone 27 which is removably mounted on the spindle and lieldagainst `inward movement by means of the shoulder 1-l formed on the spindle. The other ball bearing 13 includes a cone 15 which is threaded on the end. of the spindle and is v locked against lisplacen'ikent-nby -a lock nut 16. l

My invention consists, in the addition to the above de'scrihedstructure of two auxil iary bea-rings which may be installed vwith- Iout `altering the said structure.y As shown.

I provide an auxiliaryimier thrust bearing which is arranged'aroim'd the inner cone.27. Thisl auxiliary bearing coniprjses la race ring 17 which has a poiton extending-.between the. cone 27 and the shoulder 14, and a second race ring V1S which is interposed between the balls of the bearing 12 and the' balls` 19 of'the auxiliary thrust bearing. The dimensions of this latter bearing may be such as to supplement the action of the main bearing 12 as soon as installed, or preferably, they are made such' that the 4Patented Dec. 1 6, 1919.

bearing comes into action only .after a, slight a n K n and hub comprises a series o-f balls Whichis interposed between the race rings 24 and 25, all ot these parts being arranged around the cone 15. A washer 26. is interposed between the lock nut 16 and the cone 15 and affords an abutment 'for the race ring 25.

Thus the whole thrust bearing is arrangd around the cone 1,5 andinterposed between' the balls of.tbe bearing 13v and`waslieii26. The dimensions of this thrust'.y bearing are such vthat it takes up the end;th1ustfof the wheel hub, and preferably cornes intoaction immediat-ely after a slight" .wear 'of the cone I5. y I

#'Fromtl'ie forego-ing it will be apparent that'I-Tiave provided an exceedingly simple means for practically eliminating the wear .in the bearings of wheels orthe'type mentioned, Which `may be sold` ata reasonable .loo

1. In a wheel construction the combination with a'hub of a spindle extending therethrough, a main roller bearing between said hub and spindle near each end adapted to take radial load and end thrust7 and a removable supplemental 'bearing surrounding;`

fsaid spindle at each end on the outer side of the main beariing and adapted to take end thrust from the balls of said main bearing. 2. The combination with a motor vehicle front wheel bearing of the type including two ball bearings, one having a cone on the spindle at the inner end of the wheel hub held against inward movement by a shoulder on the spindle and the other va cone threaded on the spindle at the outer endet' the hub and secured by a lock nut; of a pair of auxiliary roller bearings, one arranged around the inner cone and having a race ring extending between the said cone and shoulder and. the other arranged around the-outer cone.

` 3. The 'combination with a motor vehicle `front wheel bearing of the type including.,r

two 'ball bearings, one having a cone on the p spindle at the inner end of the wheel hub held against inward movement by a shoul- Vder .on thev spindle and the other cone threaded on the spindle at the outer end of the hub and secured by a lock nut; of a pair of auxiliary roller bearings, one arranged around he inner cone and having a race ring eXte ding between the said cone and shoulder and the othe arranged around the outer cone, and having a race ringr extending;

bo'between said outer cone and lock nut.

4. The combination with a motor vehicle front Wheel bearing of the type including two ball bearings, one having a cone on the spindle at the inner end of the wheel hub i5/and the other a cone on the spindle at the outer end ol the hub held against movement b v a lock nut; ol a pair ot auxiliarv roller bearings, one arranged around the inner cone andthe other abent the outer `conc. said latter bearing including a race rinn extending between the outer cone and lock nut.

5.
